Flying in close formation with its twin satellite, TerraSAR-X, TanDEM-X will generate the the most consistent and highest-resolution (12 meter / 40 foot pixel pitch) digital elevation map of the Earth ever, taking three years to image all 150 million square kilometers / 58 million square miles and generating more than 350 TB of raw data in the process.
